Make a difference between code commits and translation commits

[snowparrot]

Problem

Many commits are just translation commits. If you want to see, if there was a commit on code base,
we need make a distinction.

Proposal

Some proposals:
Instead showing the amount of commits, count the code commits and the translation commits seperately.

We will want to modify this line to exclude comments with the email noreply@github.com and i18n@elementary.io

Though I am happy about your fast and positive response I think counting translation commit still has a purpose ( like for minor updates)
